If you are a fly angler and use indicators, you will really appreciate the Thingamaleader.  I was introduced to a sliding indicator set up through guides while fishing the Yakima and Methow rivers.  They made adjusting the depth for particular runs or holes very easy.  When I tried creating a reliable knot system to hold the indicator and have it easily slide up and down the line I failed miserably.  When I heard that you could buy these pre-tied set ups from Red’s Fly Shop in Ellensburg, I immediately call Joe Rotter over there and got a couple.  They come in a package with different sizes of Thingamabob indicators and cost $11.95 each.  They just attach to your line with loops.  Joe knows how effect this method of indicator fishing is and told me that they had done a video on how to tie your own Thingamaleader, and he was willing to share it.  So if you are planning a trip right away, give Red’s a call at 509-933-2300.  This is the link to the video, to tie your own: https://www.youtube.com/watch?v=scbK4QDjE0o
